The Oculus Rift is a virtual reality system that completely immerses you inside a virtual world. The device fits over your eyes like an oversized pair of ski goggles. Inside those goggles are two screens that cause your eyes to see the world around you as a fully explorable 3D space.
While using the Oculus Rift, you control your movement using a gamepad. Or, you can hold two controller devices (called Oculus Touch) in your hands to track your movement.
The Rift also tracks your head movement using a technology called Constellation. That means when you look around, it seems like you’re looking around a virtual world.
